I love Nora and Tilly so much! Eleanor and Matilda are really great together, hands down my favorite. (I know you don't want any new suggestions but since you seem to love MatildaSnow, why not also use EleanorWinter instead of EloiseWinter? Then they would both have "frosty" Christmas word mn's, better matching firsts with cute-as-a-button nn options, and no one gets left out.) Good luck! =]
